Title: Coke oven battery
IPC: C10B21/18
Filed: 1977-05-03
Abstract: 1531701 Controlling waste gas recirculation in coke ovens KOPPERS CO Inc 3 May 1977 [3 May 1976] 18481/77 Headings F4B and F4K A coke oven battery has heating flues 63, 65 67, 67 &c. extending within walls intermediate the ovens 13, 14, 15 &c. and is provided with high calorific value fuel gas through a conduit 17 that supplies fuel mixture to the heating walls. The fuel gas reaches the heating walls via conduits 35, jet nozzles 33, Venturi tubes 31 and gun flues 25. Combustion takes place in the flues of one heating wall called "on" flues and gases pass up these flues and down the flues of the adjacent heating wall known as "off" flues. After a time the gas flow in the flues is reversed. Combustion gases from the flues pass to a waste gas flue 16. Conduits 45 lead waste gases from the flue 16 to reversing valves 47, and then via ducts 51, 53 to the Venturi tubes 31. The position of the reversing valves 47 is selected so that "on" flues are supplied with waste gases from the flue 16 to dilute the rich gas supplied to the Venturi tubes from the conduit 17. When combustion gas flow is reversed in the flues, waste gases are supplied to the new "on" flue by operation of the valve 47.

Title: Magnetic transducers
IPC: G11B5/255
Filed: 1973-04-18
Abstract: 1410264 Magnetic transducers; reducing wear NORTRONICS CO Inc 18 April 1973 18757/73 Heading G5R The gap 11 of a magnetic head is situated at the crest of a convex local elevation 41, 43, the remainder of the head face 49 being coated with a material 47 having a substantially greater wear resistance than core pieces 31, 35; 33, 37 and core-piece holders 17, 18, 21. In use, the crest becomes worn to just below the level of the layer 47; which thereafter limits wear, Fig. 5 (not shown). In the four-track read-after-write assembly shown, the read and the write gaps 11 are respectively situated at the crests of longitudinally-extending elevations 41, 43, and a central shielding member 16 is situated at the crest of a similar elevation 45 of lesser altitude. The elevations 41, 43, 45 are either formed by abrading a flat head surface, Fig. I (not shown), or are preformed in the core pieces. The wearresistant layer 47 is preferably an aluminium oxide/titanium dioxide ceramic material applied by a plasma flame spray process. Compositions including chrome oxide or tungsten carbide may alternatively be used. The wear-resistant layer is finally abraded and the gaps 11 exposed.

Patent GB-631872-A (GB)
Title: Improvements in or relating to radio beacons
IPC: G01S1/02
Filed: 1946-06-25
Abstract: 631,872. Radio navigation. SADIR-CARPENTIER. June 25, 1946, No. 19023. Convention date, June 25, 1945. [Class 40 (vii)] An equisignal type radio beacon comprises a central aerial fed from a transmitter and two laterally spaced. aerials with means for alternately varying the characteristics of the lateral aerial circuits in phase opposition at a frequency of the order of audio frequencies. The laterally spaced aerials may or may not be energized. In the case where these are not energized no high frequency feeders are re. quired for the lateral aerials. Fig. 2 shows such a beacon wherein a transmitter 7 energizes aerial A. and the tuning of lateral aerials B and C is alternately varied by audio frequency modulator 6 which operating through transformer 5 causes diodes 3 and 4 to conduct during alternate half-cycles and alters the effect of the reflector aerials by damping the tuned circuits. The received modulation depth is zero along the axis and has the same value but differs in phase by 180 degrees at symmetrical points on either side of it. To identify to which side any deviation from course takes place the transmission from the central aerial may be modulated so that its modulation is in phase with that created to one side of the course and thus adds to it and subtracts from that received on the other. By inverting the phase of this modulation by keying means 8 at a low frequency and in dot-dash or similar rhythm standard equisignal indications can be obtained on the craft. Instead of diodes contact rectifiers may be used (Fig. 3, not shown) and instead of shunting the tuned lateral aerial circuits supplementary reactances may be alternately inserted and removed (Figs. 4 and 5, not shown). To obtain phase reversal of the lateral aerial currents with constant amplitude it may be arranged that the detuning effected when a rectifier is conductive is equal but opposite to that occurring when the rectifier is non-conductive. The inverter 8 may be inserted in the modulation frequency coupling to the lateral aerials instead of in the modulation feed to the central aerial. Fig. 6 shows the feed to one of the lateral aerials in a system in which the lateral aerials are energized. The characteristics of these aerials are modified by any of the means previously described (not shown in Fig. 6) at an audio frequency and phase reversing means 8 inserted in each feeder. The directly fed component of the energy may be adjusted in amplitude and phase in the coupling circuits so as to produce the desired signal when combined with that directly induced at C by aerial A.

Title: Means for enabling a craft to travel over or above the surface of water while being supported and/or stabilized thereby
IPC: B63B1/28

Abstract: 572,179. Hydroplane vessels; sails. HOOK, C. Nov. 15, 1943, No. 19041. Convention date, Nov. 3, 1942. [Classes 113 (ii) and 115] In a hydroplane vessel in which the angle of incidence of one or more submerged supporting fins, or groups of fins, is varied automatically by means of a control float skimming the surface of the water, one or more of the fins are disposed adjacent the bow of the vessel and are pivotally connected to a strut fixed relatively to the hull, whilst the float is disposed ahead of the fin, and preferably ahead of the bow of the vessel, whereby the angle of incidence of the fin is increased as it becomes more deeply submerged. Fig. 1 shows a mechanicallypropelled vessel 1 with a fixed stern fin 5 and a pair of bow fins 8 pivoted to struts 10 on a cross-beam 9, front extensions 13 of the fins being pivotally connected by links 14 to L- shaped lever arms 12 pivoted between the struts and rigidly fixed to streamlined floats 11. Fig. 4 shows a sailing vessel 15 with a sail plane 16 of aerofoil section horizontally pivoted on masts 17, the rearmost of which is swingable athwartships. Modifications of the mountings for the fins and floats are described and illustrated in the Specification, in one of which the initial angle of incidence of the fins is adjusted from within the vessel. Alternatively, the movement of the float, or the pressure thereon, may operate the fins indirectly through the intermediary of mechanical and/or electrical devices within the vessel.

Title: Improvements in gas valves
IPC: F16K5/02

Abstract: 660,785. Valves formed with seats for other valves. HARPER-WYMAN CO. July 17, 1947. [Nov. 13, 1946] 19161/47. Class 135. [Also in Group XI] A valve controlling the gas supply to a double (main and simmer) burner comprises a hollow rotatable plug 16 with a transverse passage 22 leading to the interior of the plug and a further transverse passage, not shown, which also communicates with the interior of the plug via an auxiliary valve 46, the arrangement being that, in one position of the plug, a small quantity of gas passes through the auxiliary valve and the hollow interior of the plug to the simmer burner, in a second position of the plug, a larger quantity of gas can flow to the simmer burner, and, in a third position of the plug, gas is supplied to both burners. The gas flows from the interior of the plug to a chamber 20 and thence to the burner past a needle valve 76. A further transverse passage in the plug allows gas to flow through a radial passage in the valve body, similar to the inlet passage 26, to an outlet provided with a needle valve and leading to the main burner. The passages in the valve body and in the plug are staggered both axially and radially. A further small transverse passage is provided in the plug to prevent gas from being cut off from the burners whilst the plug is being turned between two of its positions. The auxiliary valve rotates in a sleeve 42, and in order to prevent the escape of gas past the valve, an indentation 62 in the sleeve engages in a lubricant filled groove in the valve. A position indicating device 90 is provided for the plug 16.

In Fig. 1 (not shown), the joint is formed from a sheet of beryllium copper in the form of a right-angled cross, each arm of which has a circular hole near its end. Opposite arms are bent through 180 degrees so that their ends overlap in a plane parallel to the original sheet, with their holes in alignment. The overlapping ends are secured to brass blocks having a central bored spigot which is peened over the holes and receives the shaft.
